Toward the ultimate reach of current imaging atmospheric Cherenkov telescopes and their sensitivity to TeV dark matter / Montanari, Alessandro (IRFU, Saclay, DPP) ; Moulin, Emmanuel (IRFU, Saclay, DPP) ; Rodd, Nicholas L. (CERN)
Indirect detection opens a unique window for probing thermal dark matter (DM): the same annihilation process that determined the relic abundance in the early Universe drives the present day astrophysical signal. [...]

UV and IR Effects in Axion Quality Control / Burgess, C.P. (McMaster U. ; Perimeter Inst. Theor. Phys.) ; Choi, Gongjun (CERN) ; Quevedo, F. (Cambridge U., DAMTP)
Motivated by recent discussions and the absence of exact global symmetries in UV completions of gravity we re-examine the axion quality problem (and naturalness issues more generally) using antisymmetric Kalb-Ramond (KR) fields rather than their pseudoscalar duals, as suggested by string and higher dimensional theories.

Anomaly Cancellation in Effective Field Theories From the Covariant Derivative Expansion / Cohen, Timothy (CERN ; EPFL, Lausanne, LPTP ; Oregon U.) ; Lu, Xiaochuan (Oregon U. ; UC, San Diego) ; Zhang, Zhengkang (UC, Santa Barbara)
We extend our recently-proposed formalism for calculating anomalies of global and gauge symmetries using the Covariant Derivative Expansion to include a general class of operators that can appear in relativistic Effective Field Theories (EFTs). [...]
